The impact of including a rapid thermal anneal step after the extension implants is examined for a 0.15 m CMOS process. SIMS data will verify that shallower junctions can be obtained with only a single anneal cycle after the source-drain implants, implying that transient enhanced diffusion is minimal for this technology. Further, transistor data indicates that improved CMOS device performance can be obtained without the extension anneal cycle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
